Quite a bit depends on how the codebase has been written and what era are you looking. Before Java 8/9 or after it. Java code written in the recent era is pretty lean and mean.
No matter the amount of abstraction though, one rarely runs into the sort of issues in Java that Go code tend to run into frequently - causing multi-million dollar mistakes frequently even for experienced Go programmers. For loop semantics https://bugzilla.mozilla.org/show_bug.cgi?id=1619047, Unintended variable shadowing, common mistakes in slice appends/copies, slices and memory leaks, defers inside loops, nil interface vs nil, panics in go-routines. There are loads of bugs in OSS projects wrt to these usually repeated again and again.
Go is very simple to learn and very hard to master writing bug-free code. Looking forward to seeing how languages like Rust perform if/when adopted by enterprise.
